Description
[technical field]
The utility model relates to a kind of stator core press mounting tool, especially relates to a kind of motor stator core press mounting tool that big-and-middle-sized vertical type generator positioning bar is adjusted that is applicable to.
[background technology]
Existing big-and-middle-sized vertical type generator stator core press-fits technology commonly used two kinds: a kind of employing extends stator core tightening screw rods, compress iron core by special pressing plate, its shortcoming is that each type generator all will be produced pressing plate and lengthening stretching screw, versatility is poor, frock production cost height, labor strength is big.Another kind is earlier by newel school positioning bar lamination, use the umbrella shape gland when iron core precompressed and stagnation pressure, the umbrella shape gland need hang out earlier newel for making things convenient for installation, need hang away the umbrella shape gland after iron core compresses again, dress newel in school continues lamination more again, and the high more then number of occurrence of iron core is many more, it is cumbersome to operate, and because newel school dress repeatedly influence stator core centering, measurement and assembly precision, it is bigger to press-fit quality influence for the less generator iron core of air gap requirement.
[utility model content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provide a kind of can realize iron core measure, can independently carry out again stator core press-fit and have compact conformation, versatility is good, installation effectiveness is high, stator core press-fits the high motor stator core press mounting tool of precision.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of motor stator core press mounting tool, comprise measuring center post, newel base, last item, umbrella shape gland, snap ring, pressing plate and pillar, upper side and lower side at described last item are equipped with annular groove, snap ring is installed in the annular groove, utilize snap ring last item can be fixed on press-mounting platform, also the umbrella shape gland can be fixed on the proper height of last item; Be separately installed with hydraulic jack on the both sides support arm of described umbrella shape gland, this hydraulic jack is successively by pillar and pressing plate and stator core pressure connection.
Described measuring center post is the seamless steel pipe structure, and sky is enclosed within the last item outer wall, is convenient for measuring newel school in place dress; The lower end of measuring center post is fixed on the newel base, and the newel base is a Welding Structure, utilizes screw can adjust measuring center post perpendicularity.Snap ring is convenient to dismounting for dividing half part.Pillar is the weldment structure.On described measuring center post, be set with thousand fens gauge rods measuring iron core each point radius.
The beneficial effects of the utility model are: the measuring center post adopts the seamless steel pipe structure, iron core is measured and stator core press-fit can independently carry out, mutually noninterfere, the production efficiency height; The last item annular groove can be fixed on proper height with general umbrella shape gland easily, has very strong versatility, and for example my company's stator core internal diameter all is easy to use from 2700mm to 6000mm; Iron core press-fits coefficient and reaches 0.96, and the iron core tightness meets the requirements; Stator core press-fits that quality is good, and as being example with up-to-date Yun Kou power station, the iron core radius is controlled at R1360 ± 0.25mm, and wave degree is controlled in the 3mm.
